Abstract

The invention is suitable for the field of optical fiber and provides a device for generating super continuous spectrums. The device comprises a continuous wave fiber laser, a high nonlinear photonic crystal fiber and a high nonlinear normal dispersive optical fiber, wherein the continuous wave fiber laser is used for providing pump light; the high nonlinear photonic crystal fiber is welded with an output tail fiber of the continuous wave fiber laser and is used for performing nonlinear conversion on the pump light provided by the continuous wave fiber laser so as to form the continuous spectrums; the high nonlinear normal dispersive optical fiber is welded with the high nonlinear photon crystal fiber and is used for flattening and expanding the formed super continuous spectrums. The device for generating the super continuous spectrums can flatten the super continuous spectrums with high spectral intensity peaks. Simultaneously, the spectrums further expand towards a long wave direction so as to obtain high flat broadband super continuum output.

Description

technical field [0001] The invention belongs to the field of optical fibers, in particular to a device for generating supercontinuum. Background technique [0002] At present, there are two important indicators to measure the quality of supercontinuum sources, one is spectral range, and the other is spectral flatness. Most of the current research on supercontinuum generated by continuous wave pumping focuses on the expansion of the supercontinuum spectral range, but there is little research on how to obtain a highly flat supercontinuum, such as by adding double zero dispersion photonic crystal fiber The length can appropriately improve the conversion of the pump light to the long-wave direction, but the output spectral flatness has not been significantly improved. It can be seen that the problem of realizing the spectral flattening of the supercontinuum light source has not been well solved in the prior art.
